pangolin x python x mac os build failed memorandum unsolved

Overview

pangolin https://github.com/stevenlovegrove/Pangolin I tried to build it on mac using python binding, but I was suffering from an unsolvable error.

Memo 1

https://github.com/stevenlovegrove/Pangolin From here, when I tried to build using python3.6 series normally.

I got an error about ffmpeg, so first with the cmake flag -DBUILD_PANGOLIN_FFMPEG=OFF Was used. Or, I tried to save FindFFMPEG in the CMakeModules folder.

Then with cmake-> make -j

This error cannot be resolved.

Memo 2

https://github.com/uoip/pangolin I used this repository and tried the build in the same way. Regarding ffmpeg, I dealt with it as described in Note 1.

that time, https://github.com/uoip/pangolin/issues/35 Because the same problem as here occurred I overwrote all include paths with absolute paths as suggested here. (Same for eigen, gl) Then the build goes through, pangolin.cpython-36m-darwin.so Was generated, but when importing

https://github.com/uoip/pangolin/issues/26 Segfault (11) as shown here.

Memo 3

When I tried it on ubuntu18 series, Pangolin built well and imported without any problem. However, the g2opy that I wanted to build as well cannot be built here (on mac, this can be built ,,) Give up once.

A memorandum about the build of pangolin.
